Four time periods are available during week-

WAKE is the time the thermostat turns on the
heating/cooling equipment after an energy
saving period.When deciding what time to
set for your WAKE period, include extra
lead time, depending on the outside

time, to give the equipment a head start to
heat or cool the house before you get up.
(This will be a higher temperature during
heating season, and a lower temperature
during cooling season.)
LEAVE is the time period you can set for an
energy-saving temperature while you are
away at work or school.(This will be a
lower temperature during heating season,
and a higher temperature during cooling
season.)
RETURN is the time the thermostat turns on
the heating/cooling equipment after an
energy saving period.When deciding what
time to set for your RETURN period,
include extra lead time, depending on the
outside temperature and your equipment
response time, to give the equipment a
head start to heat or cool the house before
you arrive home.
